We present an imaging method that maps a 2D image into a serial time-domain waveform and simultaneously amplifies it optically. Continuous real-time images at a record frame rate of 6.1 MHz are captured using an oscilloscope.
Imaging of vapor-phase H2O2 concentrations is performed using photofragmentation LIF. An Nd:YAG-laser is used for photolysis and a dye laser for LIF on OH generated in the photolysis process. Detection limit is ~30 ppm.
Optical implementations of synthetic aperture imaging techniques provide a method of overcoming the platform constrained diffraction limit for optical imaging systems. We discuss progress in applying these methods to outdoor imaging demonstrations.
An ultrafast optical microscope capable of rapidly and sensitively acquiring wide field optical images with sub-100 femtosecond temporal resolution and micrometer spatial resolution is demonstrated for the first time.
